Groundwater is the principle source of drinking water supply and other domestic uses in urban areas

Groundwater is the principle source of drinking water supply and other domestic uses in urban areas. As by increasing population and unbridled exploitation of the available resources has caused a drastic decline of the quality and quantity of groundwater. In many developing cities including Patna, disposal of municipal solid waste(MSW) in a landfill is an issue of concern. The present research evaluated the level of ground water pollution on spatial and temporal basis near Rajendra nagar Landfill site,Patna,Bihar. All the water samples were collected in the study area during Pre-monsoon and post-monsoon seasons from April-May2017 to September-October2017. The study has been conduted and evaluated by comparing the potential of contaminats at different interval of depth and distance of Groundwater sources near landfill site, Rajendra nagar, Patna,Bihar.
The available water resource in the study area consist borewell, handpump and dug well at different depth and used as drinking and domestic purpose. Total 32 samples were collected and analyzed for various physio-chemical analysis like, ph, conductivity, total dissolve solid, total hardness, alkalinity, calcium, magnesium, phosphate, sulphate, Groundwater is the principle source of drinking water supply and other domestic uses in urban areas.

Descriptive Statistical tools especially mean, variation, standard deviation, standard error and coefficient of variation were used to analyze the basic features of the results. The study indicates that the landfill area exhibited significant contamination at certain level of depth and promoting the rate of contamination by leachate formation and shows higher concentration of conductivity, total hardness, alkalinity as well as microbial contamination show that the ground water is not potable within WHO guidelines, which ensures that the remediation action and periodic monitoring should be require to stabilize this threat to the groundwater contamination and its impact to the surrounding population.
